WebFeb 9, 2024 · The structure of a motor neuron can be categorized into three components: the soma, the axon, and the dendrites. The soma is the cell body where the nucleus lies, which controls the cells and is also where proteins are produced to maintain the functioning of the neuron. The dendrites are the branch-like structures found at the ends of the neuron. WebIn this context, the structural adaptations of neurons are notable. The shape of a nerve cell is such that it facilitates impulse transmission over long distances.
